I've got 3 SBC engines in stock.
Any thoughts on which combination of these would be best for a mid range RPM daily driver would be very much appreciated.
Trans will be a 700R4
Rear ratio is 3.08 .
Welcome Aboard! Nice to see you here. We've got a couple guys that are really good with selecting Chebby parts.. Myself. I bleed Blue but I can offer you this much. There's no substitution for cubic inches so I'd start with the 40 over block. Then select the heads that can flow the best, cam? Depends what you want to do.. Towing? Cruising? Daily Driver? All the above??? Always a compromise right!?!?! Overdrive Tranny is always a good choice now and the rear gear ratio is alright, not my first choice.. I'd be more inclined to go with 3.25 minimum or more probably 3.5 / 3.7 but that would also depend on the use. If I had to drive a long commute each day.. Then the 3.08's look much better! Let's see what Glenn has to say, he's an ace with the SBC.
